Xyrosaris Meyrick, 1907 is a small genus of the family Yponomeutidae, established by Meyrick (1907) for its type species Xyrosaris dyropa Meyrick, 1907. A total of nine species were recognized in the world. Most of species of the genus have been described by Meyrick at the early 20th century. Up to date, X. lichneuta Meyrick, 1918 has been reported from Korea. In the present study, we review the genus Xyrosaris from Korea, with two new species: X. sp.1 and X. sp.2. Key to species, illustrations of adult, male and female genitalia, diagnosis and short description are provided.

The family Thyrididae was known as a small group comprising 940 species in the world (Nieukerken et al, 2011). In Korea, the first report of the family was made by Park (1983) with four species. Later, 10 species of 4 genera was enumerated by several researchers (Park & Byun, 1990; Choi, 2005). The typical characteristics of the family Thyrididae is a window-like transparent pattern of wings. Some species in the family are classified as insect pest species (Jo, 1995). Thus, it is important to study the group for the applied fields. In this study, the reveiw of the family Thyrididae in Korea was conducted. All available materials was examined and illustrated. Also the collecting localities, illustrations of adults and genitalia are provided.

The family Platygastridae is a large group of parasitoid wasps, generally have a small body size (1-2mm). Platygastidae comprised of 5 subfamilies (Platygastrinae, Sceliotrachelinae, Scelioninae, Teleasinae, and Telenominae). Until know 6,049 species in 265 genera are reported around the world except polar regions and 96 species in 26 genera are reported from Korea. This study contains general information of Platygastrid wasps as a candidate of effective natural enemy, also provide high resolution photography to identify Korean Platygastid wasps at the genus levels.

Delphacidae is the most diverse group in the Superfamily Fulgoroidea (Hemiptera: Auchenorrhyncha: Fulgoromorpha) with more than 2000 reported species worldwide. This group is commonly called planthoppers, because most members are grass-feeding species. Some members are known as vectors of economically important plant viruses, and damage to several crops in many countries. Stenocranus is one of the biggest groups in the Delphacidae. In Korea, there have been eight recorded species. In this presentation, we present taxonomic review of the Stenocranus with a new record in Korea. Morphological characters and key to Korean species are presented.

Until now, 12 subspeceis of Eucarabus (Parhomopterus) sternbergi has been recorded in South Korea and some were described by foreign entomologist without comparative examination. In addition, most of them were not reviewed since the original description. Therefore, based on this study, all subspecies of this group in South Korea were revised taxonomically, and a new subspecific key was provided. As a result, 8 subspecies of Eucarabus (Parhomopterus) sternbergi were confirmed in South Korea and their new synonyms are as follows: Eucarabus (Parhomopterus) sternbergi sternbergi (Roeschke, 1898) = E. (P.) s. gimhwa (Rapuzzi, 2015); E. (P.) s. honamensis (Kwon et Lee, 1984) = E. (P.) s. jindoensis (Rapuzzi, 2015) = E. (P.) s. goheungicus (Rapuzzi, 2015); E. (P.) s. schnelli (Lassalle, 1999) = E. (P.) s. deogyusan (Rapuzzi, 2015).

The genus Microrhagus Dejean, 1833 is reviewed with four species from Korea: Microrhagus foveolatus (Fleutiaux, 1923), Microrhagus jejuensis sp. nov., Microrhagus mystagogus (Fleutiaux, 1923), and Microrhagus ramosus Fleutiaux, 1902. Herein, we provide a key to species of Korean Microrhagus, with diagnoses and photographs for each species.

Two species of the genus Coccura Šulc, 1908 from Korea are reviewed. Coccura convexa Borchsenius, 1949 and C. suwakoensis (Kuwana and Toyoda, 1915) were recorded from North Korea by the report of Danzig (1980). Although Kwon et al. (2003) described Coccura comari (Kunow, 1880) from South Korea, we found that this species was misidentification of C. suwakoensis. In this study, we suggest that Coccura comari (Kunow, 1880) is to be excluded from the Korean fauna. The occurrence of C. suwakoensis is also recorded from South Korea for the first time, based on the additional populations which were heavily infested on the Chinese fingetree, Chionanthus retusus Lindley and Paxton. A key to the species of Coccura known from Korea is provided with diagnoses and photographs.

The family Cicadellidae (Hemiptera: Auchenorrhyncha) is one of the largest insect families, and contains approximately 22,000 described species. All members of this group are phytophagous, therefore, many of them are known as insect pests. Additionally, some species can transfer some pathogens such as viruses and phytoplasmas to plants as a vector. Macropsis (Cicadellidae: Macropsinae) is one of the largest groups in Cicadellidae, and has a world distribution. Among them, M. mendax and M. fuscula are famous for a vector associated with phytoplasma disease in Europe (Elm yellow, Rubus stunt disease). In Korea, three Macropsis species have been recorded to date. In this talk, genus Macropsis is reviewed from Korea. Morphological information such as diagnoses and descriptions of genitalia and the key to Macropsis are presented.

A taxonomic review of the Acrotona Thomson in Korea is presented. The genus is represented in Korea by 10 speciesincluding two new species, A. koreana Lee & Ahn, sp. nov. and A. rufescens Lee & Ahn, sp. nov. Two other species,A. paeksongrica Paśnik and A. suyangsani Paśnik, are synonymized under A. pseudotenera (Cameron) and A. lutulenta(Sharp), respectively, and four species, A. grata (Cameron), A. lutulenta (Sharp), A. pseudotenera (Cameron) and A. vicaria(Kraatz), are identified for the first time in South Korea. A key to the Korean species and illustrations of habitus anddiagnostic characters are provided for the new species.

The genus Coccus is reviewed as 4 species from Korea, including a new species, C. ficicola sp. n., and a first recordof C. maloti (Takahashi, 1956). A key to four species of Coccus known from Korea is provided with diagnoses, illustrationsand photographs.

The aim of this study is to review the genus Phyllonorycter in Korea. In this study, totally 19species of the genus were recognized from Korea. Among them, four species, Phyllonorycter cretata(Kumata), P. japonica (Kumata), P. rostrispinosa (Kumata) and P. stephanandrae (Kumata) are reportedfor the first from Korea. All the known species were briefly redescribed with illustrations of theadult and genitalic structures. Also, key to the species was provided.

The cranefly genus Tipula Linnaeus, 1758 (Diptera: Tipulidae) contains up to 2,790 species in 40 subgenera distributed in all biogeographic regions. The richest fauna is known in the Palaearctic region with 1,224 speices. The Korean Tipula was recorded for the first time by Alexander in the early 20th century. According to the ‘Checklist of Korean aquatic insects (2014)’ 30 species in 12 subgenera are recorded in Korea. Baek and Bae (2016) additionally reported 5 species new to Korea. We reviewed all known species of the genus Tipula in the Korean Peninsula. We also provided a key to the subgenera and species. This work was supported by a grant from the National Institute of Biological Resources (NIBR), funded by the Ministry of Environment (MOE) of the Republic of Korea (NIBR201722202).

Tingidae (Hemiptera: Heteroptera), commonly called “Lace Bugs”, is reported with more than 300 genera and 2,500 species and widely distributed in the world. All of the members of Tingidae are phytophagous, and have associations with their host plants. Some species are known as serious insect pests in agriculture and in forestry (including landscaping trees) in many countries. In this talk, Physatocheila sp. nov. is described from the Korean Peninsula. The morphological information of the Korean congeners and a key to the Korean Physatocheila species are presented with photographs and illustrations.

The family Nabidae (Hemiptera: Heteroptera: Cimicomorpha) is a cosmopolitan family of medium-sized (4-12 mm.) predatory groups in true bugs. Among them, 10 genera and approximately 130 species are distributed in the Palaearctic region. Most Nabidae are predators on various stages of insects (e.g., aphids, leafhoppers and lepidopteran eggs and young caterpillars), but several genera within the subfamily Prostemmatinae (e.g., Prostemma, Alloeorhynchus and Pagasa) are specialized predators of true bugs, especially of the family Lygaeidae. Most Nabinae are herbicolous and arboricolous, whereas all Prostemmatinae are ground-inhabiting (in litter layer, under stones, etc.). In this talk the family Nabidae is reviewed from Korea including two unrecorded species and one new species. The morphological information such as description and diagnoses, and biological information for each species are provided.

The present study was carried out to revise the species of Chlaeniini in Carabidae from Korea, using both classic taxonomy and molecular analysis. Another aim is to decide the taxonomic position of Chlaenius micans Fabricius of which subgeneric status in the genus has been in question. As a part of the results, Chlaenius spathulifer Bates, 1873 was newly recognized to Korean insect fauna. With this new addition Korean Chlaeniini contains now in total 34 species and two genera. This study provids a key to species, photos of adult habitus, photos of male genitalia and redescriptions of 28 Korean species in Chlaeniini.

톱상어과는 톱상어목에 속하며 지금까지 2속 8종이 보고되었다. 우리나라에 서식하는 톱상어과 어류는 톱상어 1종으로 알려져 있다. 톱상어과는 주둥이 양쪽에 작고 큰 이빨이 나있으며 납작하 고 긴 것이 특징이다. 톱상어의 집단구조를 알기 위해서 4개의 지역(한국, 개체수=6; 미야기현, 개체수=1; 고치현, 개체수=1; 오키나와, 개체수=8)에서 채집된 16개체를 대상으로 형태와 분자분 석을 실시하였다. 형태분석결과 3가지의 유형으로 구분되었으며, 그 중 톱상어 A 유형은 한국과 일본에 서식하며 짧은 주둥이(전장의 26.8%), 폭넓은 주둥이(주둥이 길이는 주둥이 폭의 4.5배)를 가 지며, 톱상어 모식표본과 유사한 점에서 톱상어(Pristiophorus japonicus)로 추정된다. 톱상어 B 유 형은 오키나와에 서식하며 긴 주둥이(전장의 31.7%), 폭넓은 주둥이(5.2배)를 가져 Pristiophorus sp. 1로 제안한다. 톱상어 C 유형은 오키나와에 서식하며 긴 주둥이(전장의 31.7%), 폭좁은 주둥이 (6.3배)를 가져 Pristiophorus sp. 2로 제안한다. 나아가 톱상어 A 유형과 C 유형의 mtDNA cytb 영역을 비교한 결과 2.1~2.7% 차이를 보여 형태결과를 지지해 주었다. 향후 Pristiophorus sp. 1 및 Pristiophorus sp. 2의 분류학적 위치를 구명하기 위한 추가 연구가 필요하다.

This taxonomic study on the genus Scutellathous is only recognized a species. S. porrecticollis (Lewis, 1894) in Korea. The previous record of Athous (=Medakathous) jactatus (Lewis, 1984) is revealed as the misientification of S. porrecticollis. We also describe and illustrate Subscutellathous koreanicus gen. and sp. nov. from Korea. This new genus si compared to the most closed genus Scutellathous by the basis of diagnostic characters in generic level.
